RAIL 'WAY-SWITCH. GUARD.

Application filedDecember 22, 1924. Serial Ito/757,544.

The present invention relates to; improvements in railway switch guards and more particularly to the improvement in the guard disclosed in a patent issued to Matthew J. McNamara and to James R. Fleming, assignor of one-half undivided interest,

and numbored 1,426,583.

lhe present invention has among its principal objects to increase the useful life of the guard; to reduce the cost factor of theguard; and to facilitate the making of repairs when same arise.

Figure 1 is a plan view of a fragment of a railway switch showing in conjunction therewith a guard-member constructed and arranged in accordance with the present invention.

Figure 2 is a vertical section of a railway rail and guard member, the section being taken as on the line 2-2 in Figure 1..

Figure 3 is. a rear view of the guard member shown in Figures 1 and 2.

Figure t is a detail view showing a side elevation of a fragmentot a railway rail and a guard member constructed and arranged in accordance with the modified form of the invention.

Figure 5 is a vertical section of a railway rail and guard member, the section being taken as on the line in Figure 4:.

Figure 6 is a rear view of the guard member shown in Figures t and 5.

As seen in the drawings the switch guard embodies a deflector 11 the central ortion of which is thickened to form seating shoulders l2 shaped rest on the chair block 13. The block 13 is shaped at the rear to fit the corner of the junction oi the web 14: and the flange 15 of the railway rail with which it is associated.

The deflector 11 has an outwardly, inclined extension 16 at the edges thereof. The'inner surface extensions are-shaped in correspondence with the side of the head 1? of the railway rail and seating portions of the blocks 18. The extremities of the entensions 16 are reduced to a relatively fine edge, the arness being to receive the flange ot' the car wheel without shock and to defleet the same by causi it to slide down over the inclined f outer face the extensions. The preferred form that shown drawings, when usive of the is elongated and inclined surfaces are formed on the longer sides thereof. When thus constructed the deflectors have a series of bolt holes 18 disposed as best seen in Figure 3 of the drawings in line to receive the fastening bolts 19. The bolts 19 have a threaded end to receive the nut 20, which when set up bears against the deflector to draw the head of the bolt against the web of the railway rail, or' against a suitable washer (not shown) placed between thehead of the bolt 19 and the web of the rail. I

In some cases I prefer to hold the block 13 and deflector 11 in serviceposition by providing a projection 22 on the block 13 and a corresponding recess 23- in the back of the thickened portion of the deflector 11.

The engagement between the recess 23 and projection 22 offsets any tendency the block 13 might have or develop, to drift from under the deflector 22.

In the modified form of the invention 7 shownin Figures l to 6 inclusive, the deflector 11 is four-sided and 1S rectangular in shape, each of the edges being chamfered or lit wll also he noted that the perforation 25 with which the modified form of the provided are disposed in pairs rather :han in series, each pair of perforations are spaced apart so as to receive two of the bolts 19 instead of the four shown in Figure 3 of the drawings. The pairs of perforations 25 are disposed as shown in Figure 6 in perpendicular relation.

, When disposed in service, the deflectors are bolted to the railway rails immediately in oi the reduced end 26 of the swinging rail 2? of a railway switch. En practice this construction and arrangement results in deflecting or forcing the car wheels leterally'cut or the path of the extremity of the swinging rail 27. To this end the flange he car wheel which runs at the inside rails rides Cl SUI 31GB 18 of the deflector in such aving the deflector the upon and slides down the Figures t to 6 inclusive, four inclined surfaces 16, may be placed inservice, thereby increasing the useful life of" the deflector by four. 7

Claims:

1. A railway switch guard embodying a deflector member having a plurality of inclined surfaces for engaging the flange of a railway wheel to shift the same toward the center of a railway track; and means for attaching the same on a railway rail in advance of the reduced end of a swinging switch rail in such manner that any desired one of said inclined surfaces maybe placed in operative position.

2. A railway switch guard embodying a deflector member having a plurality of inclined surfaces for engaging the flange of a railway wheel to shift the same toward the center of a railway track; and means for attaching the same on a railway rail in advance of the reduced end of a swinging switch rail, said means embodying a chair block adapted to rest on the flange. of a rail for supporting said deflector member.

3. A railway switch guard embodying a deflector member having a plurality of inclined surfaces for engaging the flange of a railway wheel to shift the same toward the center of a railway track; and means for attaching the same on a railway rail in advance of the reduced end of a swinging switch rail, said means embodying a removable ehair shaped to fit the railway rail and an extension at the rear of the deflecting member adapted to extend over and rest upon said chair. 1

4. A railway switch guard embodying a deflector member having a plurality of inclined surfaces for engaging the flange of a railway wheel to shift the same toward the center of a railway track: and means for attaching the same on a railway rail in advance of the reduced end of a swinging switch rail, said means embodying a removable chair shaped to fit the railway rail, and an extension at the rear of the deflecting member adapted to extend over and rest upon said chair; and means for preventing the disalignment of said chair and deflecting member.

5. A railway switch guard embodying a symmetrical removable deflector member having a plurality of inclined surfaces for engaging the flange of a railway wheel to shift the same toward the center of a railway traek, said inclined surfaces being adapted to be successively placed in operative position.
